BOX-OPERATING MECHANISM FOR LOOIVIS.

Application filed January 12, 1918.

To all whom t may concern.'

Be it known that I, JOHN T. KENNEDY, a citizen of the United States residing at West Paterson borough, in the county of Passaic and State of New Jersey, have in- Vented certain new and useful Improvements `in Box-OperatingV Mechanisms for Looms, of which the fol owing is a specilication.

This invention relates to box-operating mechanisms of theclass in which the box shifting is `obtained from intermeshing gear members, the driver of which has its periphery made up of adjoiningtoothed and blank segments and the driven member of which is shiftable to clear ,the driver' longitudinally of their axes. The invention has for its object, among others, to provide a box-operating mechanism of this class, the main part of which shall be self-contained and adapted tov be applied to already-existing looms by a simple manner of fastening and shall include a fixed structure or bracket of such form as at once to afford a substantial support to the moving elements and limit the movements of certain of them in the direction of shifting the shiftable or driven gear member.

In the accompanying drawings,

Figure l is a side elevatiotn of a box operating mechanism embodying my invention;

F 1g. 2 is a plan view of the essential elements;

Fig. 3` is a sectional view on line 3-3, Fig. 4; and

Fig. 4; is a rear elevation.

a is the shuttle-box structure; b the boxlever connected therewith, and c a pitman connecting the box-lever with a rotary part to be described.-

d is the continuously rotating driving gear member fixed on a going Shaft a suitably journaled in the loom frame e, said member having the blank and toothed peripheral segments d 0l.

In a frame or bracket which I bolt to the side of the loom frame, is journaled a shaft g having affixed thereto 'a disk It against whose periphery bears a springpressed lever 7b which (the disk having its periphery flattened at diametrioally opposite points, as shown) holds the shaft against rotation at each half-revolution thereof. Ilille crank t' on the outer'end of the shaft is Specification of Letters Patent.

the gear member /c is in the same plane as the gear member d. Member'z is engaged with the spline j on the shaft, so that it Vrotates with but may slide on the latter out of the plane to intermesh with member d and so as to impinge against the near bearingportion f of' the bracket f, as shown by dotted `lines in Fig. 2.

A flexible means n, as a wire or cord, may extend from lever m to a pattern or like mechanism for shifting said lever contrary to its spring and hence member 7c out of the plane Where it will intermesh with member CZ.

So long as member c is in the normal (or full-line) position the member d will in each revolution, by its toothed part 0l, turn member lc a half-revolution and leave it at dwell, thus in a series of such half-turns of member c causing the boxes to rise and fall at regular intervals, it being understood that one of such half-turns in each instance results in pitman c being depressed and through lever Z2 raising the boxes to bring the lower box in line with the shuttle race of the batten, and that the other half-turn in each instance results in pitman c being raised and through lever Z) depressing the boxes to bring the upper box in line with the shuttle race. When member 7c is withdrawn to the dotted-line position, Fig. 2, the boxes will remain Astationary with" one or the other in alinement with the shuttle-race, and this condition-effected by the pattern-mechanism acting through connection n and lever mvvill prevail until the pattern mechanism allows member 7c to return under the influence of the spring controlling lever m, whereupon the boxes will be caused by gears d and c to rise and fall again at regular intervals.

In view of the construction and arrangement of member 7c with respect to member cl already pointed out, to Awit, that said inem-v ber 7s, has its teeth all in the same plane as the periphery of the member cl and arranged to successively intermesh with the geartoothed segment thereof on successive revolutions of member d and (in the illustrated construction.) is shiftable out of the plane Where the teeth of said members Will intermesh, though normally held in said plane, it Will be obvious that my construction is not only simpler and more substantial and durable than others of its class heretofore devised but that Where (as is generally the ease) the shuttles are the most of the time called at regular intervals it reduces gear shifting (or equivalent) to the minimum. That is to say, Where the general rule is, for example, black and White filling to alternate regularly on every two picks, no shifting affecting the gearing occurs at all; such shifting only occurs When the shuttle delivering one of such colors is to remain in action longer than the usual time, or when the goods being Woven requires the shuttles to remain in action for irregular periods.

In the present case, Where each revolution of the driving member produces a half-revolution of the driven member, the latter may have tWo diametrioally opposed teeth short`4 ened, as at 7u le so that the blank (Z oi" member d Will clear the same.

Having thus fully described my said invention, What I claim as new and desire to secure by Letters Patent is '2 In combination, the loom frame, a shaft journaled therein, a shuttle-box structure to be shifted, a toothed driving gear on said shaft, a bracket secured to said frame and having spaced bearing portions, and means to transmit shifting motion from said gear to said structure including a rotary member journale-d parallel With the shaft in and Confined by said bearing portions against longitudinal movement, a toothed driven gear splined on said member and shiftable thereon into and out of the plane of the driving gear and adapted to mesh with the ,latter When in said plane, the shifting movement of the driven gear being limited in one direction by said member and in. the other by one of said bearino` portions, means to shift said driven gearbbaek and forth, and means to operatively connect said structure with an eccentric point of said member.

In testimony whereof I affix my signature.

JOHN T. KENNEDY.
